"Massacre everyone in that land."
Three chapters later
"Sir, it appears they've killed all the monsters and are...eating them."
"WTF, boi?"
(Not sure it'll actually take three chapters, I just wanted to say a funny prediction)
"Yes sir.. they did turn them into delicous dishes like pizza, pastadishes, pigs in blankets,,..
"ENough damnit! send our best killers after them!"
"Ok."
later
"uh... sire? the monsters ate the killers."
"But didn't you say the people ate the monsters?"
"turns out they did tame few of them..."
"FFFFFUUUU."
